Long Period Grating Sensor to monitor Fuel Quality

Rosane Falate, José Luís Fabris, Márcia Müller and Hypolito José Kalinowski Centro Federal de Educação Tecnológica do Paraná Av. Sete de Setembro, 3165 – 80230-901 Curitiba, Brazil e-mail: rfalate@cefetpr.br We describe the production and characterisation of Long Period Gratings in fibre optics. The gratings are written in standard single-mode fibre using the electrical arc technique, while their transmission spectrum is used to control the grating length. Optical characterisation and wavelength dependence with temperature and refractive index of the external medium are shown. An application of the LPG as a sensor to monitor the fuel quality (Brazilian standard mixture of ethanol and gasoline) is presented.
